NGC 7822 - Ced 215
Cepheus
Penryn, California
September 2007
FCL-90 II (ag, ST-4)
ST-10XME, LRGB, 5 minute subs

A faint emission/SNR type nebula in Cephus is located approximately 1.5 degrees North of Ced 214. 

Note - the two bright stars at top center are HD 224825 and HD 225123 (left to right).  Image orientation is CCW  from the top NESW.

  The NGC/IC Project (Project) revised the NGC 7822 coordinates because of conflicting records by J. Draper and J. Herschel, this in addition to Roberts mis-identification of  Ced 214 (from note in Cederblad catalog) as NGC 7822 caused the Project to assign NGC 7822 to a spot on the outer edge of Ced214.

The following 15'x15' image is from the DSS for the coordinates of NGC 7822 as modified by the  Project.


  The Project did keep the original size  (20' x 4') which more fits the Herschel's object but seems hard to reconcile to the above object.  The Project also references Ced 214a and 214b which do not appear in the original Cederblad catalogue.   Note - the two bright stars are (top) HD 224992 and (bottom) HD 225216), image orientation is CCW from left NESW.
  

Of real interest is the fact the visual observing report used by the Project reported visual identifying faint nebula at the original NGC 7822 location but was unable to identify nebulosity in either Ced 214 or the project location for NGC 7822.  Herschel saw it, Draper didn't but cautioned his pointing might not have been accurate and Roberts used 90 minutes photo plates to detect Ced 214 and didn't even address the nebula at the Herschel location  (Cederblad did use the Robert plates).

  Note the Project indicated the new location was also cataloged as Ced 215 generating another catalog discrepancy for some future project to correct.  The following are the notes from the original Cederblad catalog - 

214 The nebula surrounding the two stars +66 1676 = HD 224992, and
214 +66 1679 = HD 225216 = Boss 39. R. Erroneously identified as NGC 7822
214 by Roberts in (624). (630 Pl 20).
215 NGC 7822 = GC 5051 = h 2302. R. The coordinates and the description given
215 by John Herschel must refer to the nebulous cluster containing the HD
215 stars: +68 1423 = HD 225123, and +67 1588 = HD 224825.
215 Compare (630) Pl 20. (114, 304, 631).
